Embedded Systems Conference 2015 Schedule – May 6-7, 2015

The Embedded Systems Conference took the name “Design West” for a couple of years, but this year, there’s no mention of Design West, and the Embedded System Conference 2015 will take place in Boston, MA, US on May 6-7, 2015. The 2-day event will have a demo hall, and well as sessions divided into 8 tracks: Connected Devices and the IoT Embedded Software Design Hardware: Design, I/O and Interfacing Prototyping Embedded Systems Design Software: Design, Languages, & Quality Fantastical Theater Teardowns The full schedule has now been posted, and I’ll build a virtual schedule with some of the sessions provided. Wednesday May 6, 2015 8:00 – 8:45 – Understanding Google/Nest Thread by Michael Anderson, Chief Scientist, The PTR Group, Inc. The IoT will live or die based on its connectivity. In examining existing wireless protocols, Google/Nest found most of them lacking. In order to address the needs for low-power wireless […]

Intel Curie Board Designed for Wearables is Powered by Quark SE SoC

Intel announced the Edison board at CES 2014, a board targetting wearables and IoT applications about the size of an SD card. At CES 2015, the company has gone smaller, by unveiling the button-sized Intel Curie module powered by a new Intel Quark SE SoC with a motion sensor, Bluetooth Low Energy connectivity and battery charging capabilities. Intel Curie specifications: Low-power, 32-bit Intel Quark SE SoC 384kB Flash memory, 80kB SRAM Low-power integrated DSP sensor hub with a proprietary pattern matching accelerator Bluetooth Low Energy 6-axis combo sensor with accelerometer and gyroscope Battery charging circuitry (PMIC) The module runs an unnamed open source RTOS, and the company will provide IQ software kits for references applications for wearables, such as counting steps, apps for mobile device, and so on. Intel Curie is expected to be found in smart products such as rings, bags, bracelets, pendants, fitness trackers and buttons. There’s basically no […]

Fernvale Open Source Hardware IoT Board Based on Mediatek MT6260 SoC with GSM Connectivity

Andrew Huang (Bunnie), an hardware engineer, known for hacking the original XBOX, and more recently for Novena open source laptop, has decided it could be interesting to reverse-engineer Mediatek MT6260 processor, as in China, it’s difficult to get documentation, SDK, and tools if you don’t commit to purchase X chips, where X is a rather large number. He and others also checked whether their work could be open sourced legally, and assert their “fair use” rights to reverse-engineer hardware and firmware. And so Fernvale project was born both as a technical challenge and to make a point. MT6260 is a $3 ARM7EJ-S processor clocked at 364 MHz with 8MB built-in RAM, interfaces such as I2C, SPI, PWM, UART, as well as LCD and touchscheen controller, and audio codec, battery charger, USB, Bluetooth, and GSM support, which make the $6 Atmel MCU used in Arduino board look expensive. The main differences […]
